Abstract

The details of design of a multilayer structure for optimum longitudinal Kerr magneto-optic effect are established theoretically on the basis of a general matrix theory of structures containing a single transparent ferromagnetic film. It is shown that the multilayer structure, which is essentially a Fabry–Perot type of interference filter with a nickel–iron film as part of the spacing layer, is better by a factor of 1.8 (on the basis of signal-to-noise ratio associated with the Kerr effect) than an opaque film of nickel–iron coated with a single matching layer of zinc sulfide.
